Gm3 x5 e53 3.0d
 

Hello
Neeeew problem with my X, my servotronic stoped working and central locking for rear doors. Front doors works. Is this problem with my gm3 modul or something else. The fuse are all ok. Is it normal when i pull the fuse for servotronic my alarm turn on? For all your help i thank you..

Servotronic (steering) isn't working - what fault codes do you have (Carly is handy)?

If your central locking doesn't work for the rear doors - do you have the same problem with the inside central locking button, turning the key in the door and the remote button on your key?

Difficult to answer third question - we don't know what alarm you have (factory, other)?

Other suggestion - create a signature with the model, version and year of your car - it helps us know quickly what you drive (and possibly to help with a solution).

I lock the car the alarm is on, and you can open rear door normaly. The alarm is original.
The problem is for all method of locking..

This morning I tried it with my spare key. It worked I could lock, unlock the car and even servotronic started to work. It put smile to my face. I drove to work and all was woorking. When I left work the car was normal and in the middle of the way, servotronic stoped working and ofcourse the locking of rear door. When I synchronized the key it worked again. my questions is why both car keys loose connection, synchronize...

Perhaps the battery is going bad in the key.

I bought used gm3. How is the right way to change it?
1. Disconnect batery
2. Change gm 3
3. Connect batery
4. Code it with bmw scanner 1.4.0
5. Pray the used gm3 is good

Is this right.
